For Inorganic Wood Treaters:
Dedicate material handling equipment (forklifts, pettibones, boots, etc.) to drip pad to ensure that process pollutants are not tracked off the pad.
Store and handle treated and untreated wood (and associated stormwaters) separately. Store treated wood (including blocks and stickers) under roofs, tarps, or plastic wrap while on site. Pave treated wood storage areas.
Adjust drip pad storage times to account for variables (such as ambient temperature, humidity, wood species, moisture content, etc.) to ensure wood is drip-free and surface-dry before it is moved off the pad.
Optimize drainage from treated wood (e.g. angle trams or poles and use adequate blocking (more blocks on longer trams).
Regularly schedule cleaning/sweeping of paved areas. Pressure wash and/or dry vacuum treated wood storage yard during dry season. Collect wash water and pump into recovery water tank for use in process.
Ensure wood stock is clean prior to treating. Use water, compressed air, and/or agreements with suppliers. Perform visual inspections at time of delivery.
Ensure all process water is collected and recycled to the process treatment system. Drip pans under trams, should be sloped to return to recovery system.
Final vacuum applied in treatment cylinder to remove excess preservative. Use hot water treatment in a separate, dedicated retort following pressure treatment
Completely enclosed treatment building; including tank farm, retorts, transfer table and drip pad.
Pressure treat with Ammoniacal copper quatenary (ACQ), or other less toxic alternatives, as a substitute for CCA. (Be prepared to market these products aggressively, because demand is low at present.)
For Organic Treaters using penta:
Cooling tower modifications to reduce the PCP contribution to stormwater.
Install panels on tower to prevent droplets from escaping due to wind.
